le yto the length of e t :Surrounding the stern is a relativelyadjustable sleeve 7 -having one rend engaging the lower side of theWasher 5`andits` lower end engaging the Washer 8. AThev lower end of thestem has a pair4 of diametrically ar#l ranged apertures 9 to receive apivot screvvf'` 10, .the latter extending through thearmsll and 12 of anadjusting member 13, the amis of the latter being provided Withvcanisurf faces adapted to coperatevvith thelunder side of the Washer 8 asthe adjusting'rneinber is turned about the pivot screwlasvlan axis.'"70The adjusting member is located at" af relatively loW p'oint on thebracket, and it', may n be provided with a lamp socket, or'it may be,provided, as shown, with an ornamental bulb 14, a threaded rodfl5passing axially therethrough and yhaving its ends threaded, to tathreaded aperture 16 in the adjusting member, vthe bulb serving as ahandle by'. means of which the adjustingA lever may be turned about itspivot. The high part 17 of the cam is preferably arranged inline ywiththe rod 15 in order that the latterrnay oc-r cupya vertical positionWhen the sections of the chandelier arejin locked relation."l a Thelocking `medium is operated by a rela# tive axial movement between thestern and its surrounding sleeve, and it may becom- `posed of an annularelastic sleeve 18 sur`.

rounding the stem between the Washers 4` and 5, and it is made of rubberor other suitable material that is capable of being com` pressed in thedirection of one'dimension and correspondingly expanded in the directionof anotherdimension, rotation of the adjusting lever to a point Whereits stem occu ies a vertical position causing a relatively ongitudi` nalmovement of the stem and sleeve, proximating the Washers 4 and 5, andthereby compressing the sleeve in the direction of its -axis andcorrespondingly expanding it in the ioodire/etmaal?:itspdieyleterithere@ n soabein f,

in orderjthat they may be -'adjusted axially". thereof to, ,vary thecompressing 'action `c1'1 1 110I the *elastic sleeve when the adjustingrneiib'ev is turned into locked position. y i

The lamp attaching d'evices may be arranged in any suitable manner onthe relatlve y adjustable section,.a bracket 19 being secured, in thepresent instance, to the lower end of the sleeve-7 and serving tosupport the lamp carrying arms 20, the sleeve .and stem being providedat `a point adjacent to the brac etwith registering a ertures 21 throu hwhich the conductor cor 22 leading to t e lamps passes. The upper endsof the conducting cords extend upwardly through'the hollow stem, andthey are coiled in the form of a helix above the u per end of theadjustable'section. The coi ed arrangement of the conductor is capableof a relatively axial elongation and compression, as the adjustablesection is moved longitudinally of the casing, so that it is unnecessaryto connect and disconnect the conductors whenever the chandelier isadjusted, and the use of sliding contacts and other unreliable devicesis avoided.

What is claimed is 1. In a chandelier, the combination with a relativelystationary section embodying a ltubular casing, of a relativelyadjustable section mounted telescopically of the casing and govided witha stem having an abutment ed on the upper end thereof, a sleeveadi'ustable longitudinally of the stem, an annuar body of ex ansiblematerial surrounding the stem and aving one end engaging the saidabutment on the .stem and its opposite end enga the upper end of thesleeve, and a device or adjusting the stem longitudinally of the sleeveto ,compress the expansible medium longitudinally and expand 1ttransverselly.

2. n a chandelier, the combination with a stationary section embodying atubular casing, of a relatively adjustable section mounted to operatelon tudinally thereof and embodying a stem aving an abutment at itsupper end adjustable longitudinally thereof, an a sleeve surrounding thestem and movable lon 'tudinally' thereof, an expansible medium iavingits ends engaging the said abutment and the upper end of the sleeverespectively and arranged to be compressed longitudinally and expandedtransversely when the stem and sleeve areo erated relatively, and a campivoted on t e lower end of the stem and coperating with 'the lower endof the sleeve'for adjusting the latter and the stem longitudinall 3. Ina chandelier, t e combination with a stationary section embodying atubular casing,l of a relatively adjustable section embodying a stemhavin an abutment at its up er end and adapte to operate longitudi-- nay ofthe casin a sleeve surrounding the stem andadjusta le longitudinallythereof,

an annular expansible body surrounding the Stem and interposed betweenthe abutment thereon and the up er end of the sleeve, and

an adjustable mem er plvotallyattached to the lower end ofv the stem andhaving arms arranged at opposite sides thereof and provided with camsurfaces adapted to coperate with the lower end of the sleeve to operatethe latter and the stem longitudinally to compress the annular bodylongitudinally and expand it transversely.

, 4. In a chandelier, the combination with a stationary sectionembodying a tubular casing, of an adjustable section adapted to carrylamp attaching devices and embodying a stem having its upper endthreaded, and an abutment ted to operate on said threads, a pair ofcoperatively arranged washers loosely Afitted onv the stem, an annularbody of expansible material surrounding'the stem between the washers, asleeve mounted to I operate longitudinally of the st'em having its up erend engaging one of, the washers, and a evice connecting the-lower endsof the stem and sleeve for adlusting them lon itudinally to compress taxially.

5. ln a chandelier,` the combination with a e expansible bo y supportingsection embodying a tubular' casmovement between the adjustable andsupporting-sections. j A

6. In a chandelier, the combination with a stationary section, of anadjustable section mounted in co erative-relation therewith andprovi'ded wit lamp attaching devices, of

va locking device interposed between the sections for 'retainingthem infixed relation, and

' a device for operating the locking device embodying a cam pivoted toturn 1n a vertical plane on the lowerl end of the'adjustable section andarranged to occu y a position in alinement with the axis of`t e sectionswhen the locking device is in locked position and an ornamental deviceforming-an operating handle for the cam.

In testimony that we claim the foregoing as our own, we have heretoaffixed our ignatures in the presence of two witnesses.
